hydrogenation reactions catalyzed by frustrated Lewis pairs, were synthesized in high yield under mild conditions from triaryl boranes, ammonium or phosphonium halides, and triethylsilane. The kinetics and mechanisms of the reactions of these hydridoborate salts with benzhydrylium ions, iminium ions, quinone methides, and Michael acceptors were investigated, and their nucleophilicity was determined and compared
在温和的条件下,由三芳基硼烷,卤化铵或phospho和三乙基硅烷以高收率合成了数种tri芳基铵和三芳基硼氢化铵,它们是受挫的Lewis对催化的氢化反应的中间体。研究了这些硼氢化物盐与苯甲酸铵离子,亚胺鎓离子,醌甲基化物和迈克尔受体的反应动力学和机理,并确定了它们的亲核性,并将其与其他氢化物供体进行了比较。
